Abstract:
Studies to evaluate different PGRs viz., NAA (40 ppm) and CPPU (10 and 20 ppm) was undertaken at Instructional-Cum-Research Orchard of the Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri. The PGRs were sprayed thrice during mango fruit development stages viz. at mustard stage, pea stage and at marble stage. The maximum number of fruit per panicle at pea stage (14.54), marble stage (4.39) and fruit harvested per panicle (1.52) was in the treatment T10. The treatment T15 (CPPU-20 ppm: at Marble + at pea) increased fruit length (10.56 cm), diameter (6.43 cm) and average fruit weight (328.73 g) indicating superiority of the treatment for increasing yield. The treatment T8 (CPPU-10 ppm: Pea Satge) produced maximum number of fruit per tree (362.33). Yield of fruit (107 kg/tree and 10.7 t/ha) was maximum in the treatment T10. The quality of fruit in terms of TSS, total sugars, reducing sugars, non-reducing sugars and acidity were non significant. The results in general indicated that the foliar spray of PGRs during mustard, pea and marble stages of fruit development were beneficial for increasing yield of mango cv. Keshar. Application of PGRs at mustard + pea stage was found effective in increasing fruit number and weight than single application at any stage. Among the different PGRs and stages of application, CPPU 10 ppm at mustard + pea stage recorded maximum yield 107.00 kg/tree and 10.7 t/ha.
